Joseph Stiglitz

Joseph Stiglitz received the 2001 Nobel Prize in Economics along with Akerlof and Spence for his work on information economics. He served as chairman of Clinton's Council of Economic Advisers and as Chief Economist of the World Bank, from which he resigned in 2000 citing disagreements with IMF structural adjustment policies. His books "Globalization and Its Discontents" and "The Price of Inequality" became influential critiques of financial market liberalization. Stiglitz has been a vocal advocate for financial regulation reform and a critic of economic austerity policies. His academic work on asymmetric information produced the Stiglitz-Weiss model of credit rationing, showing that banks may deny credit to some borrowers even at higher interest rates — a foundational insight in understanding how credit markets operate under information asymmetry. He also developed the Greenwald-Stiglitz theorem demonstrating that markets are generally informationally inefficient in the presence of imperfect information, challenging the efficient market hypothesis.
